GB 50160-2008 \"Code for Fire Protection Design of Petrochemical Enterprises (2018 Edition)\", 6.2.23: Storage tanks for flammable liquids shall be equipped with level gauges and high-level alarms; where necessary, automatic interlock systems to shut off the feeding facilities shall also be installed； An automatic dehydrator should also be installed. 6.3.10 Liquid ammonia storage tanks shall be equipped with level gauges, pressure gauges, and safety valves ； Low-temperature liquid ammonia storage tanks should also be equipped with temperature indicators. 6.3.11 Liquefied hydrocarbon storage tanks shall be equipped with level gauges, thermometers, pressure gauges, safety valves, as well as high-level alarms and automatic interlock systems to cut off feeding at extremely high levels. Configuration: Level gauge + high-level alarm + interlock shutdown device

SH/T 3136-2024 \"Code for Safety Design of Spherical Storage Tanks for Liquefied Hydrocarbons\" (Draft for Approval) 5.3.1 Spherical storage tanks for liquefied hydrocarbons shall be equipped with at least two sets of remote continuous level gauges; it is advisable to use level gauges based on different measurement principles, and at least one of these sets shall have the function of providing an on-site level indication. Configuration: 2 sets of remote level gauges + local level indication function

SH 3136-2003 \"Code for Design of Spherical Storage Tanks for Liquefied Hydrocarbons in Petrochemical Industries\" 5.3.1 Spherical storage tanks for liquefied hydrocarbons shall be equipped with local and remote level gauges; however, glass plate level gauges should not be used. The level gauge used should be safe and reliable, and the number of openings in the spherical storage tanks for liquefied hydrocarbons should be minimized as much as possible. Configuration: 2 sets of level gauges (local + remote transmission)

SH/T 3007-2014 \"Code for Design of Tank Areas in Petrochemical Storage and Transportation Systems\" 5.4.1 Storage tanks with a capacity greater than 100 m³ shall be equipped with remote liquid level measurement instruments. 5.4.5 The level measurement instruments for the high and low level alarm signals of the storage tank shall be separate continuous level meters or level switches, and the alarm signals shall be transmitted to the automatic control system. Configuration: 2 sets of level gauges + (high-high alarm and low-low alarm set independently)
